ASTER
is an imaging instrument flying on Terra, a satellite launched in December
1999 as part of NASA’s Earth Observing System. ASTER
collects data in 14 different spectral bands which vary in spatial resolution
from 15 to 90 meters (see table below). KansasView
members have been using the first three 15-meter bands in various research applications,
including looking at the water quality of ponds.

These false color composites
of Forbes Field airport south of Topeka, Kansas were acquired by the
ASTER (left) and ETM+ (right) sensors.
